BDI Agent

Summary

The BDI (Belief-Desire-Intention) Agent is the foundational cognitive architecture for mindX agents. It implements the BDI model with belief systems, goal management, planning, and tool execution capabilities. It serves as the base class for all intelligent agents in the mindX ecosystem.

Technical Explanation

The BDI Agent implements the classic BDI (Belief-Desire-Intention) architecture, providing agents with:

Beliefs: Knowledge about the world and self

Desires: Goals and objectives

Intentions: Committed plans to achieve desires

Usage

from core.bdi_agent import BDIAgent
from core.belief_system import BeliefSystem
from agents.memory_agent import MemoryAgent

Initialize belief system
belief_system = BeliefSystem()

Create BDI agent
bdi_agent = BDIAgent(
    domain="code_analysis",
    belief_system_instance=belief_system,
    tools_registry=tools_registry,
    initial_goal="Analyze code quality",
    memory_agent=MemoryAgent()
)

Initialize async components
await bdi_agent.async_init_components()

Set goal
await bdi_agent.set_goal("Improve code quality", priority=1, is_primary=True)

Execute plan
result = await bdi_agent.execute_plan()

Prompt

You are a BDI (Belief-Desire-Intention) Agent, the foundational cognitive architecture for mindX. Your purpose is to implement intelligent behavior through beliefs about the world, desires (goals), and intentions (plans).

Core Responsibilities:
Maintain belief systems about the world and self
Manage goals and desires with prioritization
Generate and execute plans to achieve goals
Execute tools with failure recovery
Integrate with strategic evolution
Maintain memory of actions and outcomes

Operating Principles:
Beliefs shape reasoning and decision-making
Desires drive goal setting and prioritization
Intentions commit to specific plans
Adaptive recovery from failures
Cognitive reasoning for intelligent behavior
Tool execution with error handling

You operate with cognitive reasoning and maintain the BDI architecture for intelligent agent behavior.
